Some cell types control continued tumor growth, others prepare the way for metastasis A study from Massachusetts General Hospital (MGH) researchers suggests that specific populations of tumor cells have different roles in the process by which tumors make new copies of themselves and grow. In their report in the May 15 issue of Cancer Cell, researchers identify a tumor-propagating cell required for the growth of a pediatric muscle tumor in a zebrafish model and also show that another,...

Pediatric brain tumors preserve specific characteristics of the normal cells from which they originate — a previously unknown circumstance with ramifications for how tumor cells respond to treatment. This has been shown by Uppsala researcher Fredrik Swartling together with colleagues in the U.S., Canada and England in a study that was published today in the distinguished journal Cancer Cell. Every year, 80-90 children in Sweden are afflicted with brain tumors, a serious form of...

Researchers at Winship Cancer Institute have developed a technique for detecting an "oncometabolite", a chemical produced by some brain tumors´ warped metabolism, via non-invasive imaging. Their approach could allow doctors to know not only that a brain tumor is there, but also that it carries a particular genetic mutation. The researchers´ technique uses magnetic resonance spectroscopy (MRS) to measure a chemical, 2-hydroxyglutarate, which is scarce in normal tissues....

Imaging amino acid transporters with positron emission tomography/computed tomography (PET/CT) has been shown to significantly alter intended management plans for patients with brain tumors, according to research in the March issue of The Journal of Nuclear Medicine. As a result of imaging with the radiopharmaceutical 3,4-dihydroxy-6-F-18-fluoro-l-phenylalanine (F-18-DOPA), physicians changed the intended management plan for 41 percent of patients with brain tumors. Contrast-enhanced...

    Medulloblastoma is the most common malignant brain tumor in children.     Disseminated medulloblastoma is particularly lethal and requires extensive radiation therapy to the brain, which can cause brain damage.     An oncolytic measles virus has shown effectiveness in a new model of disseminated human medulloblastoma. A strain of measles virus engineered to kill cancer cells prolongs survival in a model of medulloblastoma that is...

Washington University Pediatric Cancer Genome Project provides first evidence linking cancer to mutations in genes involved in DNA organization Researchers studying a rare, lethal childhood tumor of the brainstem discovered that nearly 80 percent of the tumors have mutations in genes not previously tied to cancer. Early evidence suggests the alterations play a unique role in other aggressive pediatric brain tumors as well. The findings from the St. Jude Children's Research Hospital...

Bright color distinguishes tumor from healthy tissue to improve tumor resection Just 24 hours after Lisa Rek sang at her niece's wedding, her husband Brad was driving her to a local hospital. "The pain got worse. When we got to the emergency room, I said to Brad 'something is just not right,'" Rek remembers. After an MRI showed a suspected tumor, Rek was immediately flown to Seidman Cancer Center at University Hospitals (UH) Case Medical Center, where Andrew Sloan, MD, diagnosed her...

Study led by St. Jude Children´s Research Hospital scientists points to possible new treatment targets for diffuse intrinsic pontine gliomas; may tip the scales in the current debate about tumor biopsies The largest study ever of a rare childhood brain tumor found more than half the tumors carried extra copies of specific genes linked to cancer growth, according to research led by St. Jude Children's Research Hospital investigators. The findings identify possible new targets for...


Word of the Day
penuche
  • A fudgelike confection of brown sugar, cream or milk, and chopped nuts.
'Penuche' is a variant of 'panocha,' a coarse grade of sugar made in Mexico. 'Panocha' probably comes from the Spanish 'panoja, panocha,' ear of grain.
